Add functionality to connect CyBear Jinni Hub to WiFi network

[guyluz11]

We need to add the option to connect a new Hub device to the local WiFi.

This functionality can be done using Security Bear.

Security Bear will automatically connect to WiFi in range with the name and password CyBear Jinni and can receive new WiFi credentials with gRPC request.

The app should take the user the following setup

1. The user will insert his desired WiFi name and password.
2. The app or the user will open a hotspot with the name and password CyBear Jinni.
3. The app will scan if Security Bear got connected to its hotspot.
4. Whan connection is established it will send the Security Bear server the WiFi info from step 1.
5. After data got successfully the phone will get reconnected back to the WiFi.
6. The user will be redirected back to the Connect to Hub Page which should now find the hub in the local network.
